Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610954, here are decompositions:

43 + 31610911 = 31610954
61 + 31610893 = 31610954
163 + 31610791 = 31610954
181 + 31610773 = 31610954
313 + 31610641 = 31610954
367 + 31610587 = 31610954
373 + 31610581 = 31610954
433 + 31610521 = 31610954

Showing the first eight; more decompositions exist.
